我创建了这样的表。。

CREATE TABLE test1.mytest (
    id text,
    year text,
    time bigint,
    crtby text,
    data text,
    postid text,
    upby text,
    PRIMARY KEY ((id, year), time)
) WITH CLUSTERING ORDER BY (time DESC)

我想根据时间键对数据进行排序。

SELECT * FROM test1.mytest WHERE id ='b' ORDER BY time asc ALLOW FILTERING ;

当我尝试上述命令时，我得到

InvalidRequest: Error from server: code=2200 [Invalid query] message="ORDER BY is only supported when the partition key is restricted by an EQ or an IN."
